VERTICALLY-CORRUGATI-:o CAN.

SPECIFICATION forming part of Letters Patent No. 616,246. dated December 20, 1898.

Application filed June 16, 1 89 8.

To all whom it may concern:

Be it known that I, JOHN C. MILLIGAN, a citizen of the United States, residing at New York, (Brooklyrg) county of Kings7 State of New York, have invented certain new and vuseful Improvements in f'ertically-Corrugated Cans, fully described and represented in the following specification and the accompanying drawings,forming a part of the same.

The object of the present invention is to form a cellular construction for an ash-can whereby great strength and lightness can be secured and great durability may be obtained, 'lo'etect this object, I form the can-body with rectangular cells of the same cross-section throughout their length, so that such cells may be filled when desired with rectangular wooden staves having parallel sides adapted to support the walls of the cells under pressure; To make the cells of rectangular section, I form the can-body with aseries of ribs or folds which are disposed radially, and thus at right angles to the cylindrical surface of the body. Such radial disposition of the ribs imparts to the sheet metal the highest degree of resistance to lateral pressure, while it forms, with the body, cells of substantially rectangularcross-section in which parallel wooden staves of the same cross-section throughout may be inserted. Staves of similar cross-section throughout their length are readily made by machinery and are also slipped into the cells from the end with great facility.

To facilitate the construction of the cells and the introduction of the staves therein, the can is made of cylindrical form, which makes the cells straight from end to end. 'A series of yauxiliary sheet-metal coverings are provided to inclose the cells o1" staves and necessarily add a certain degree of strength to the structure.

The essential feature of the construction is the cylindrical body, the radial ribs, and

sheet-metal coverings adapted to incltse the cells. y

The invention will be understood byre'ference to the annexed drawings, in which,-

Figure 1 is an elevation of the can, shown in section at the right-hand side of the line new. Fig. 2 is a horizontal section of onehalf the can, taken on line 2 2in Fig. 1. Fig.

Serial No. 683,5 99. (No model.)

3 is an enlarged View of a part of the sheetmet-al shell, provided with theribs 'or corrugations required to-form the cells, the View being taken from the edgefof the sheet and one of the cells being provided with a wooden stave and sheet-metal covering. Fig. -l rep# resents the sheet metal formed with loops from which the ribs may be shaped by suitable tools. the covering-plates for inclosing the cell. Fig. 6 is' an edge view of the indented strip to form the hoop to Surround the can.

The cells are formed upon the body of the can by providing a sheet of metal A of suitable length and width and bending the sheet metal transversely at intervals, as shown in Figs. 3 and 4, with loops b', which maybe afterward`shaped by suitable `tools. toV ...flor-gn the flded ribs b, at right angles to the body ofthe blank, with T-heads or iianges c upon the edges of suoli ribs. .Figs 1 and 2 show the can-:body made from such blank bent into cylindrical form,with the cells a opening out- 5 is an elevation of one of4 wardly.'= The cells made by this construction are parallel from top to bottom, so that'par allel staves d may be readily inserted in the same fr m the ends.

The outer sides of the cells may be closed to coven the wood by an auxiliary sheet-metalcovering, in Fig.y as a parallel strip of sheet metal 71., which shown in Fig. 3 inserted in one of the cell over the wooden stave d, beneath the andvsuch covering is representedilanges I which serve to retain' the covering in place;

v It is bbvious that the sheet of metal- Ais easily prepared, with the cells, to form the body of the can and is readily bent into eylindrical shape and the ends joined, when 'the staves and coverings can be quickly applied to the cells. The body of the can is then of the same thickness throughout from top to bottom and is protected at the top by a U-shaped band C', which is .suitably secur-ed upon the sheet-metal body.

A bottom B is shown formed integr-al with.

a U-shaped band C and reinforced by a wooden disk g, the bottom being secured by nails g', inserted into the wood through holes f' in the band.

A hoop E is shownencircling the middle of the can-body and is formed of band-iron indented transversely, as shown in Fig. U, to embrace the outer projections of the corrugations'or ribs. The indentations in the hoop or band form shoulders which are adapted to positively engage the projecting portions of the ribs, andV thus hold them from displacement, which materially strengthens the body by keeping the ribs in their radial relation to the sheet metal A.

The auxiliary covering for be made of a continuous sheet tions like those designated 'L' z' in Fig. (5, so as to embrace the flanges c and hold the ribs from displacement, as just described in reference to the band, and the construction shown in Fig. 2 would represent such sheet in combination with the body A and radial ribs as correctly as it representsthe hoop E, which is shown in Fig. 1. 1

I am aware that barrels and cans have been fluted and ribbed to increase their strength and that structures have been formed ot' a series of stifening-pieces and a sheet of flexible material passed alternately over the inner and outer faces of such pieces; but I am not aware thatanyshcet-mctal body has been 'formed with a series of' closed rectangular cells of their length and extended from the top to thc bottom of the can, so that the cell-partitions arc radial and the cells rectangular, with the ends closed by suitable bands. This design, greatly facilitates 'the construction of the blank, the introduction of the stavcs, the covering of the cells, and the shaping of the entire shell into cylindrical form as well as the application of the bottoni at one end and the top band at the other, vhile it secures a construction of great strength and elasticity to resist the lateral blows and strains to which such causare subjected.

The material is cheap, and the article is thus produced at a low cost in proportion to its strength.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A can having a closed bottom and open top and formed with a cylindrical body havthe cells may with indentathe same cross-section throughout ing a s crics of rectangular cells of the same cross-section throughout their length, extended from the top to the bottom of the can, parallel staves of wood adapted to insert in the cells from the end of the saine, and bands C, C operating to close the ends of the cells and retain the stavcs therein, as and for the purpose set forth.

2. In a can, the combination, with a sheetmetal cylindrical body formed upon one side only with a series of vertical folded ribs, of a series of auxiliary sheet-metal coverings held in place by engagement with the ribs, and forming with the same a series of closed cells of equal cross-section from the top to the bottom et the can, as and for the purpose set forth.

3. The blank tor forming a cylindrical canbody with vertical cells of the same cross-section throughout their length, consisting of the metallic sheet A provided upon one sid.1 with the transverse series of loops Il', adapted for the forma-tion et cells, in connection with auxiliary coverings for such cells, substantially as herein set forth.

4. In acan, the combination, willi a sheetmetal cylindrical 'body having upon one side the folded radial ribs b having the T-hcads r, as set forth, ot rectangular wooden stavcs fitted 'to such cells, and the auxiliary coverings h fitted to the cells within the flanges of the T-hcads, as and for the purpose set forth.

5. In a can, the combination, with a/cylindrical can-body having a series ot' "crtical corrugatons forming vertical closed Ycells withsradial ribs between the cells, of the hoop E having the series formed at intervals therein to fit upon such ribs and engaging the edges of the same to positively prevent their displacement, substantially as herein set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing wi t nesscs.
